Hi
Can you post the full error as seen in the console?

the doc states

If the file is not available or an error occurs, null will be returned and an error message will be printed to the console. The error message does not halt the program, however the null value may cause a NullPointerException if your code does not check whether the value returned is null.

==> double check that all file names are correct.

Memory limit of the JVM? Double check if all the images are correctly loaded (are you getting in the console an exception “java.lang.OutOfMemoryError: Java heap space”)
